Product description

Brand Name: Dexcom G7 Continuous Glucose Monitoring System Product Name: Dexcom G7 CGM iOS App Model/Catalog Number: SW12300 Software Version: version 2.8.0 and earlier Product Description: Dexcom G7 CGM iOS App Component: Dexcom G7 Continuous Glucose Monitoring System

Reason for recall

The affected devices are the Dexcom G7 Continuous Glucose Monitoring System (CGM System) using iOS, watchOS and Android App software (versions 2.8.0 or earlier) and Dexcom ONE+ CGM System using iOS and Android App software (versions 1.4.0 or earlier), henceforth referred to as the App. The affected App does not provide an expected "Sensor Failed" alert when the transmitter sends a "transmitterFailed" error message to the App when the CGM experiences a hardware or firmware failure. Instead, the App ends the CGM sensor session, stops reporting glucose values and displays the Start Sensor screen or No active sensor message without alerting the user, which can lead to missed detection of a hyperglycemic or hypoglycemic event and a delay in treatment.
